A hydroponic system is best if is airtight and recycles the humidity. As the extreme weather conditions of climate change results in desertification, in general humanity has to build it's habitats similarly to Mars or Moon bases. This way the water conservation is absolute and the collection of additional water is just for surplus and backup reasons. Not to mention reverse osmosis is a perfectly viable solution around oceans. It's a technology which works.
